Weed Management Thoughts: Planting Cotton and Soybean in 2 to 3 Weeks
By Daniel Stephenson, Ph.D.

To manage weeds preplant, meaning two to three weeks prior, or preemergence, an application of paraquat at 0.5 to 0.75 lb/A plus a residual herbicide is needed to remove existing weeds and maintain fields weed-free. If paraquat is applied preplant, a second application may need to be applied at planting to remove any remaining green vegetation.
If 2,4-D, dicamba, Elevore, and others may be applied, read the label because there are planting restrictions for cotton and soybean. However, there are no planting restrictions for Enlist Duo and Enlist One in Enlist crops or Engenia, FeXapan, Tavium, and XtendiMax in Xtend crops.
